ROAD DRAG.

Application filed. February 18, 1924. Serial No. 693,500.

T 0 all whom it may concern:

Be it known that I, ROY Coon, a citizen of the United States, residing at Windsor,

county of lVeld, and State of Colorado, have invented certain new and useful Improvements in Road Drags; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters. of reference marked thereon, which form a part of this specification.

This invention relates to road drags and has particular referenceto improvements in the adjusting means therefor.

It is customary, where dirt roads are in use, to drag thesame after a rain has moistened the surface of the road. The purpose of the dragging is to make the road smooth and to give it a convex transverse curvature.

' For the purpose of properly smoothing the road surface, drags of various kinds have been invented, some of which have been manufactured and sold in considerable num' bers. a

My improved drag, briefly described, consists of two drag sections, each of which comprises three or more scrapers pivotally connected at their ends to longitudinal bars so that-each section may be made into a rectangle orinto a parallelogram with alternately acute and obtuse angles. The trans verse angular scrapers are also pivoted so as to rotate on an axis parallel with the plane of the section and are yieldingly held in adjusted position about this axis. two sections are connected at one end by a short link and at the other end by a longer link so that they are angularly related to each other. The long link is adjustable so that the angle between the sections can be made as large as desired so as to fit the drag to roads of different widths.

My invention can be best described when reference is had to the accompanying drawings in which the present preferred embodi- Inent thereof isillustrated, and in which:

Fig. l is a perspective view of the drag in assembled position and adjusted for moving the dirt towards the center to form a crown or convex surface;

Fig. 2 is a section taken along line 22, Fig. 1;

Fig. 3 is a plan view showing the drag The . pair of lugs 24 between which reversed. for use in flattening a road surface;

Fig. 4 is a section through one of the scrapers, said section being taken substantially on line 22, Fig. 1, and shows the scraper tilted; and

Fig. 5 is a section taken on line 55, Fig. 3.

Numeral 1. designates the longitudinal bars, of which there are two to each section. Pivotally connected to these bars are pivots 2, each of which has an enlarged head 3 which is provided with a transverse opening within which is journaled the end 4 of the axle member 5 (Figs. 4 and 5). The axle members 5 are secured to the ends of the angles 6 in the manner shown in Fig. 5. To the vertical flange of each angle 6 I secure a steel plate 7. .At a point substantially midway between the ends of angles 6, I secure arms 8 in the'manner shown in Figs. 2 and l. Parallel bars 9 are pivotally connected to arms 8 by means of bolts 10. The upper ends of arms 8 have openings for the reception of a rod 11. Pins 12 pass through the bar and form a stop for the arms 8. Surrounding bar. 11 and abutting arms 8 are helical springs 13 that are held under compression by means of the pins 14. Pivoted to one of bars 9 at point 15 is a lever 16. This lever has a longitudinal slot for the re ception of a bolt 17 which is secured to the rod 11. A notched segment 18 is secured at its ends to one of bars 9 andthe notches cooperate with the plunger 19, which passes through openings in guides 20 andis forced downwardly by means of a spring 21. It is now evident that by moving the lever 16 about its pivot 15, the angular relationship of the angles 6 and the bars 1 may be adjusted to the extent desired and held in adjusted position.

' he springs 13 permit the transverse members to yield if they should strike a stoneor if for any other reason they should be subjected to a severe strain. A diagonal bracing member 22 is connected with one of the pivots 2 and has a slot 23 that connects with another of the pivots 2. By means of this diagonal bar, the horizontal angular relation between the bars 1 and the angles (5 can be adjusted and held in adjusted position.

Secured to each of the inner bars 1 is a is pivoted one end of the toggle member comprising of work, the long link case. A pin 29 in members '25 and 26. These members have each a plurality of holes 27 ior the reception of a pivot pin 28. By placing pin 28 in different holes, the length of the link can be adjusted to suit the requirements of the the end of member 25 prevents the link from collapsing when subjected to pressure. Ears 30 and '31 are secured to the front end of each section and to these the chain -32 is connected in the manner shown in Fig. 1. The chains serve to connect the drag to the tractor or with the "teams -as the case might be.

It sometimes happens that the roads become too convex and that it is-necessary to flatten them. When this is the case the sections are transposed, the short link is moved to the front end-of the sections in the mannershown in Fig. 8 and the long, adjustable link is moved to the rear and connected to the lugs 24 which have been provided for this purpose. When the sections are connected as shown inFi-g. 3 and are pulled along the road, they will move the ground outwardly, thereby flattening the road.

When the drag is to be moved along the road without doing any appreciable amount 7 is removed and the diagonal adjusting bar 22 loosened so as to permit the sections to :be collapsed "as much as possible. a

If there should be a stone embedded in the road surface er someother solid body,

of the section, means for angular relation of the -scrapers the scrapers, as they strike the same, will yield owing-to the action of spring 13, and

permit-the scraper to yield.

By means or the diagonal bar 22, the to the bars 1 can be adjusted in the ilila l'le of the section and by means of the leverlfi, the angular relation of the scrapers can be adjusted about their axes.

Having nowdescri'bed any invention, what I claim as new is: v

1; A roaddr'ag section comprising a pair of parallel bars, said bars having pivots connected thereto at spaced intervals, each of said pivots having transverse openings forming bearings, angular scraper members pivotally mounted in said bearings, and means for adjustin the angular relationship of the bars anc scrapers in the plane adjusting the angular scrap e'rs having their scrapers angular'ly in said bearings, said last-named means having resilient means for yieldingly holding the scrapers in adjusted I position.

2. A road drag section comprising, in combination, a pair of spaced parallel bars provided with spaced openings for the reception of pivot members, pivots in said openings, each pivot having an enlarged portion provided with a transverseopening for the reception of an axle member, angular soralperimembers having their ends attached to the aide members, means for changing the angular relationship of thescrapers and the parallel bars in the plane of the sections, said scralirers about said axlemembers, and resilient means for permitting each scraper member to rotate about its axis to a limited extent. 7 v V 3. A road drag section comprising a pair of spacedba'rs having spaced openings, pivots said pivots having theirlower ends enlarged and provided with transverse openings forming bearings, a {plurality of parallel ends provided with axle members adapted to enter said bearings,a diagonal brace members-a tending from one of said barsv to the other, said member having a longitudinal slot, a bolt secured to one or said bars and extending through the slot for clamping the brace member to the bar, each of saidscraper members having an arm secured thereto and extending upwardly therefrom, said arms having openings in their upper ends for the reception of a bar, a pair of bars pivotal ly secured to the arms at a'point near the scrapers, a 'lian-dle jpivotally connected to said bars and also connected to the *bar-lpassingth-ncugh the opening in the upper ends or said arms; a step (12:) on said last named bar for cooperating with said arms to prevent IHOVQIHESIIC-UlifilQOf in one direction, a spring on the bar, one end engaging :one side of one of the arms and the other end engaging a step, and means for holding the lever in any adjusted position.
